Yes, the liquidsoap language is a functional language. Hence, it is not
possible to change the value of a variable. This is done by redefining a new
variable.
For that reason,
x = y
is a boolean, true if x = y and false otherwise.
In some cases, however, this is not possible to redefine the variable
You can use the string.ref operator. This operators returns two functions, one
for reading the current registered value, and another one to register a new
value.
In your precise case, you can do even better, and avoid string.ref. This goes
like this:
def liveStart(headers)
log("[LIVE-START]: live source goes up! Switching from playlist...")
title = headers["ice-name"]
ignore(server.execute("liveMeta.insert title=\"#{title}\"))
end
liveInput = input.harbor(id="live",
"live.ogg",
buffer=10.,
password=livePasswd,
on_connect=liveStart)
liveInput = insert_metadata(id="liveMeta", liveInput)
That way, a new metadata will be inserted each time the harbor input receives
a new connection.
